Definitions
- This invention relates to a board connector for mounting on a circuit board.
- the fixing portions are integrally formed on and project respectively from wall surfaces of longitudinally-opposite ends of the housing of a generally elongated rectangular tubular shape.
- a circuit board-side fixing surface of each of these fixing portions is held against a predetermined position of a surface of the circuit board, and the screw members are passed through the circuit board from a reverse surface thereof (a surface facing away from the surface to which the connector is fixed), and are threaded respectively into the screw holes of the fixing portions, and are tightened, and by doing so, the housing is fixed in an upstanding condition to the circuit board.
- the problem that the present invention is to solve is to enable a compact design of the circuit board to be achieved and also to enhance the degree of freedom of the design of the wiring pattern.
- this is invention provides with a board connector comprising a circuit board, a housing comprised of a synthetic resin and mounted in an upstanding manner onto the circuit board, and a fixing portion integrally provided with the housing and having a screw hole into which a screw member passed through the circuit board is threaded, the fixing portion adapted to fix the housing to the circuit board by tightening the screw member, wherein the fixing portion is provided in a projecting manner near a proximal end portion of the housing at one side of a longitudinal outer wall surface of the housing, and a fixing surface of the fixing portion adapted to be fixed to the circuit board is formed into a shape so as to restrain an end face of the housing from lifting from the circuit board when the fixing portion is fixed to the circuit board by a tightening force of the screw member.
- the fixing portion is provided at the one longitudinal outer wall surface of the housing, and by doing so, for example, a widthwise dimension of the circuit board can be reduced, and therefore a compact design of the circuit board can be achieved. Furthermore, since any fixing portion is not provided at the other longitudinal outer wall surface of the housing, a wiring pattern can be freely installed on that portion of the circuit board adjacent to the other longitudinal outer wall surface of the housing, and therefore the degree of freedom of the design of the wiring pattern can be enhanced.
- a fixing portion is provided only at one longitudinal outer wall surface of a housing and also a fixing surface is formed flush with an end face of a proximal end of the housing, the fixing portion can be compressively deformed or the circuit board can be compressively deformed by a load due to the tightening of the screw member relative to the fixing portion, depending on the material, the tightening force, etc., so that the anti-fixing portion side of the housing can be lifted to be inclined.
- the fixing surface of the fixing portion is formed into such a shape as to restrain the end face of the housing from lifting from the surface of the circuit board at the time when the fixing portion is fixed to the circuit board by the tightening force of the screw member, and therefore a compressive deformation caused by the tightening load can be compensated for. Therefore, the housing can be prevented from being inclined.
- the fixing surface may be formed as a slanting surface which projects toward the circuit board gradually in a direction away from the housing, or a projection may be provided at a portion of the fixing surface that is opposite to the housing with the screw hole disposed therebetween.
- the compact design of the circuit board can be achieved, and also the degree of freedom of the design of the wiring pattern can be enhanced.

- a screw hole 6 (see Fig. 3(c)) having a screw groove formed in an inner surface thereof is formed in the fixing portion 5.
- the screw hole 6 is formed to extend in a direction of the height of the housing 3, and a screw member (for example, a screw) 7 passing through a through hole 2b of the circuit board 2 is threaded into the screw hole 6, and the screw member 7 is tightened, and by doing so, the housing 3 is mounted in an upstanding condition on the circuit board 2.
- a bottom surface (fixing surface 5a) of the fixing portion 5 is formed into such a shape as to restrain the end face (the mounting surface 3d) of the housing 3 from lifting from the circuit board 2 at the time when the fixing portion 5 is fixed to the circuit board 2 by a tightening force of the screw member 7.
- This fixing surface 5a is formed, for example, to have a slanting surface 8.
- the slanting surface 8 is formed into such a slanting shape that the whole of the fixing surface 5a projects toward the circuit board 2 gradually in a direction away from the housing 3.
- An inclination angle of the slanting surface 8 is within such a range that a compressive deformation caused by a tightening load of the screw member 7 can be compensated for by the slanting surface 8 so that the housing 3 will not be inclined, and the inclination angle can be arbitrarily set by the material of the fixing portion 5 and the tightening force of the screw member 7.
- the slanting surface 8 inclines the whole of the fixing surface 5a, it is not limited to this construction, and part of the fixing surface 5a may be formed into a slanting shape.
- Fig. 2 (a) to (b) Fig. 3 (a) and Fig. 3 (c)
- the slanting surface 8 is shown in an exaggerated manner for better understanding.
- connection portions 4a of the connector terminals 4 projecting from the mounting surface 3d of the housing 3 are opposed respectively to the corresponding connection holes 2a (see Fig. 3(c)) of the circuit board 2, and also the screw holes 6 of the two fixing portions 5 are opposed respectively to the two through holes 2b of the circuit board 2.

- a compressive deformation, occurring when fixing the fixing portion 5 to the circuit board 2 by the tightening force of the screw member 7, can be compensated for by the slanting surface 8, and therefore the housing 3 can be prevented from being inclined.
- fixing portions are provided only at one longitudinal outer wall surface of a housing and also a fixing surface of the fixing portion is formed flush with a mounting surface of the housing, the fixing portion can be compressively deformed or the circuit board can be compressively deformed by a load due to the tightening of the screw member relative to the fixing portion, depending on the material of the synthetic resin, the tightening force, etc., so that the anti-fixing portion side of the housing can be lifted, and the housing can be inclined.
- the slanting surface 8 the compressive deformation caused by the tightening load is compensated for by the slanting surface 8, and therefore the housing 3 can be prevented from being inclined.
- the angle of this slanting surface 8 is an arbitrary angle for compensating for the compressive deformation, and is arbitrarily set depending on the material of the fixing portion 5 and the tightening force of the screw member 7.
